Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If one rigid member is coupled to multiple rigid members using a central coupling shaft inserted through overlapping members, then the coupling structure is achieved, but the assembly process becomes time-consuming
Solution Approach 1:
The coupling structure is divided into multiple independent coupling parts (first coupling part, second coupling part, third coupling part) distributed at different positions on the rigid members. Each coupling part can be engaged independently, allowing parallel assembly operations and eliminating the sequential bottleneck of inserting a single central coupling shaft through multiple overlapping members.
Solution Approach 2:
The invention transitions from a single-point coupling (central shaft) to multi-point coupling by adding coupling parts in the vertical dimension (stacked arrangement). This spatial distribution of coupling points allows simultaneous engagement of multiple coupling parts, dramatically reducing assembly time while maintaining structural integrity.
2Adaptability or versatility
If multiple coupling structures are assembled with multiple junction points, then complex shape variations and three-dimensional configurations are enabled, but the device complexity increases
Solution Approach 1:
The coupling structure is divided into modular coupling parts that can be independently configured. Each coupling part consists of standardized elements (convex parts, concave parts, engaging parts) that can be combined in various arrangements to achieve different shapes and configurations without requiring entirely new designs for each variant.
Solution Approach 2:
The coupling parts are designed with universal engagement mechanisms where convex parts can engage with concave parts in multiple orientations and positions. This universality allows the same basic coupling components to serve multiple functions and create various three-dimensional configurations, increasing adaptability without proportionally increasing complexity.
